Neutron pickup onKr84

The ${}_{}{}^{84}{}_{}{}^{}\mathrm{Kr}({}_{}{}^3{}_{}{}^{}\mathrm{He},\alpha ){}_{}{}^{83}{}_{}{}^{}\mathrm{Kr}$ reaction has been studied at a bombarding energy of 18 MeV. The isotopically enriched ${}_{}{}^{84}{}_{}{}^{}\mathrm{Kr}$ target was contained in a gas cell with no entrance window. Excitation energies and angular distributions were obtained for 16 levels up to 2735 keV excitation energy in ${}_{36}{}^{83}{}_{}{}^{}\mathrm{Kr}_{47}^{}{}_{}{}^{}$. A distorted-wave analysis was used to determine $l$ values and spectroscopic strengths. The pickup of neutrons from $1g$, $2p$, and $1f$ orbitals was observed.
